Light spots and Yellowing old leaves

[weeed]

Hello,
Bruceberry Auto
ph water around 6,5
day 29
light 85w
temperature ~30 or less

Few days ago on older leaves saw lighter spots and leaves start yellowing. Added some Bio bloom (nitrogen 2%, phosphorus 7%, potassium 4%) and a little Calmag but it didn't help. now they dry up. What should I do?

Take them off and don't panic. Older leaves die off. However, looks like your watering practice needs improvement. Are you letting the pot dry out before watering again?

Yes, it takes like 1,5/2 days
